Single-Parent Family Certificate 2027: Requirements and How to Apply

If you are raising your children on your own, there is finally a national law that recognizes your family. Royal Decree-Law 35/2026 (Real Decreto-ley 35/2026), published in the Official State Gazette (BOE) on November 11, 2026, creates the single-parent family certificate (título de familia monoparental): an official document, valid throughout Spain, that will prove you are a single-parent family before any public authority or organization. In addition, from January 1, 2027 a mother or father raising two children alone is treated as a large family (familia numerosa) and the special category of large family changes. The royal decree-law also extends the Maintenance Payment Guarantee Fund (Fondo de Garantía del Pago de Alimentos).

A warning from the start: the single-parent family certificate cannot be requested yet. It will be issued by the autonomous communities (comunidades autónomas), and the benefits can be requested from January 1, 2027. If you want to know whether your family qualifies or how to prepare the application, you can write to Fernanda Vargas on WhatsApp or book an appointment on Calendly. In this guide we explain who can request the certificate, what the requirements are, its two categories and which advantages are already law.

What Royal Decree-Law 35/2026 Is and When It Applies

Royal Decree-Law 35/2026, of November 10, on urgent measures for the recognition and protection of single-parent families and other family support measures, has two chapters. The first regulates the protection of families with a single parent and creates the single-parent family certificate. The second extends protection against unpaid child maintenance. Its final provisions also amend Law 40/2003 on the Protection of Large Families and the regulation of the Maintenance Payment Guarantee Fund.

The royal decree-law itself explains why it is approved as a matter of urgency: according to the 2025 Living Conditions Survey by the National Statistics Institute (INE), households made up of one adult with dependent children have a risk of poverty or social exclusion rate of 50.6%, compared with 25.7% for the population as a whole. Of the roughly 1.95 million single-parent households, 81.1% are headed by women.

The dates you need to be clear on:

• Publication: BOE of November 11, 2026.
• Entry into force: November 12, 2026, the day after its publication.
• Single-parent family certificate and the reform of large families: take effect from January 1, 2027.
• Autonomous communities: have six months from the entry into force to adapt their rules.

The sixth final provision sums it up as follows:

«The autonomous communities shall have a period of six months from the entry into force of this royal decree-law to adapt their rules to its provisions. Notwithstanding the above, the date from which the exercise of the benefits and rights included in this royal decree-law may be requested is January 1, 2027.»

There is one more step worth following: like every royal decree-law, it must be submitted to the Congress of Deputies within thirty days of its promulgation for Congress to rule on whether to validate or repeal it (Article 86.2 of the Constitution).

Which Families Are Considered Single-Parent Families

Article 1 of the royal decree-law defines which families can be recognized as single-parent families. It is not limited to a mother or father who lives alone with their children: it also includes some cases where there are two parents.

Single-parent families are:

• A family formed by a single parent and one or more minor children over whom they have care and custody.
• A family formed by a single person who has sole guardianship of one or more minors, or who lives with minors in permanent foster care or in care with a view to adoption.
• A family formed by a single person with one or more adult children over whom they hold representative guardianship (curatela representativa) or similar support measures for the exercise of legal capacity.

And, even when there are two parents, it also applies when:

• Care and custody belongs exclusively to one of them and that parent has no right to receive child maintenance (the law speaks of «annual maintenance payments»).
• The mother has been a victim of gender-based violence by the other parent and exercises parental authority and care and custody, guardianship, representative guardianship or similar support measures over her children.
• One of the parents is forcibly absent and cannot exercise their parental responsibilities (for example, due to imprisonment or admission to a health facility) for a foreseeable period of one year or more. In that case, the family is made up of the other parent and the children who depend on them.

An important nuance: if you have sole custody but the court set child maintenance payable by the other parent, you do not fit the first case with two parents, because the law requires that there be no right to receive maintenance. You may fit another case (for example, gender-based violence) if its conditions are met. If you have doubts about your case, it is worth reviewing it with the judgment or agreement in hand.

Requirements for the Children: Age, Living Together and Financial Dependence

For the General State Administration to recognize or maintain single-parent family status, Article 3 requires the children to meet these conditions:

• Age: be single and under 21. There is no age limit if they have a disability rating of 33% or more or are unable to work.
• Extension to 26: the limit rises to 26 if they are studying (university, vocational training or other studies suited to their age and qualifications or aimed at getting a job) and, in any case, in families where the single mother is a victim of gender-based violence.
• Living together: live with the parent. Temporary separation for studies, work, medical treatment, rehabilitation or other similar reasons does not break the cohabitation.
• Financial dependence: it exists when the child’s annual income does not exceed 100% of the current IPREM (the public income index), including extra payments (or, if unable to work, when their pension does not exceed that amount, unless they receive a non-contributory disability pension, in which case there is no limit). Also when the child contributes to supporting the family and the parent is unable to work, retired or over 65, provided that the parent’s income does not exceed 100% of the annual IPREM, including extra payments.

In addition, no one can belong to two family units at the same time.

And there is a rule worth knowing before you request the certificate. Article 3.3 says:

«3. Single-parent family status shall be lost, for the purposes of this royal decree-law, at the moment the person responsible for the family unit marries another person, forms a civil partnership (pareja de hecho) or any of the requirements established in the law ceases to be met.»

Special Category and General Category

As with large families, single-parent families are classified into two categories (Article 4).

The special category covers:

• Families with two or more children.
• Families with one child, when the family’s annual income, divided by the number of members, does not exceed 150% of the IPREM in force, including extra payments.
• Families with one child who has a disability rating of 33% or more or is unable to work.
• Families in which the parent themselves has a recognized disability of 33% or more or is unable to work.

All other families fall into the general category.

For example, a single mother with one child, with no disability in the family and income above that limit, would be a single-parent family in the general category. If she had two children, she would move into the special category.

The Single-Parent Family Certificate: Who Issues It, Validity and Renewal

Article 5 creates the single-parent family certificate. These are its main rules:

• Who issues it: the autonomous community (or the cities of Ceuta and Melilla) where you are domiciled, after an application and verification of the requirements.
• Validity: throughout Spain, with no additional formality. It will include a digital certification with the same validity as the physical format.
• Individual documents: the autonomous communities may issue a document for each family member proving that they belong to the family and its category.
• Effects: from the date you submit the application until the end of its validity.
• General validity: until the youngest child turns 21.

There are also special validity periods: until the youngest child who is studying turns 26; for as long as the disability, inability to work or dependency lasts when the certificate or the category depends on it; five years for a certificate granted on grounds of gender-based violence; one year, renewable, in cases of imprisonment or admission to health facilities; and the same duration as the foster placement in temporary foster care.

Two obligations you should not forget:

• If you do not request renewal when the validity period ends, the certificate stops having effect.
• You must report any change in the family unit that affects the certificate within a maximum of three months. Failing to meet these obligations may constitute an administrative offense under Article 18 of the Large Families Law.

Single-Parent Family with Two Children: Treated as a Large Family

This is probably the change with the greatest impact. From January 1, 2027, the new Article 2.2 of Law 40/2003 treats as a large family «The parent in family situations where there is only one, with two daughters or sons».

Until now, as a general rule, a family needed three children to be a large family, except for some equivalent cases with two children (for example, when one of them has a disability). With the reform, a mother or father alone with two children will also be able to hold the large family certificate.

Do the advantages of the two certificates add up? Not necessarily. Article 5.9 states that the single-parent family certificate is compatible with the large family certificate, but:

«although benefits of the same kind or nature deriving from those certificates shall not be cumulative, unless the corresponding rules provide otherwise.»

In other words, if both certificates entitle you, for example, to a discount on the same service, in principle you will not be able to apply both at once, unless the rules for that discount say otherwise.

The reform also widens other equivalent cases. For example, from 2027 one or two parents with two children are treated as a large family when both parents have a disability, or at least one has a disability rating of 33% or more (until now 65% was required), or they are unable to work. And a registered civil partner is also considered a parent (ascendiente).

What Changes for the Special Category of Large Family

The royal decree-law also lowers the number of children needed for the special category of large family, with effect from January 1, 2027:

• Until December 31, 2026: special category for families with five or more children, families with four children of whom at least three come from a multiple birth, adoption or foster placement, and families with four children whose annual income per member does not exceed 75% of the minimum interprofessional wage (salario mínimo interprofesional).
• From January 1, 2027: special category for families with four or more children, families with three children of whom at least two come from the same multiple birth, adoption, foster placement or care with a view to adoption, and families with three children whose annual income per member does not exceed 150% of the IPREM.

Each child with a disability or unable to work still counts as two when determining the category (new Article 4.2 of Law 40/2003, which keeps the previous rule).

What happens to the certificates you already have? The single transitional provision sets three rules:

• Large family certificates already issued remain valid until their renewal or expiry date, unless under the new rules the family must move to another category.
• Families with a general category certificate who have four children, or three of whom at least two come from a multiple birth, adoption or foster placement, are automatically classified in the special category.
• Families with three children who meet the new income limit must apply for reclassification, proving that they do not exceed that limit. It is not automatic.

What Advantages the Certificate Gives and Which Are Still Pending

Caution is needed here, because the royal decree-law mainly sets mandates for public authorities, not discounts with a specific amount. What the law says:

• Equal income thresholds: when economic criteria are used to grant aid, public authorities must adjust them so that single-parent families are, at least, on the same thresholds as two-parent families with the same number of children (Article 2.3).
• Birth, care and childrearing benefits: the income limits for accessing them may be raised for these families (Article 6.1).
• Minimum living income (ingreso mínimo vital): access is guaranteed on equal terms with two-parent families, including the possibility of living with other relatives without losing the supplement (Article 6.2).
• Employment: employment programs will promote training, retraining and preferential access to training plans, particularly for mothers, with schedules compatible with school hours and childcare services (Article 6.3).
• Scholarships: preferential treatment in scholarships and study grants, in accordance with national rules; those rules will be reviewed within two years (Article 6.4 and fifth final provision).
• Transport, culture, sport and leisure: the competent public authorities will set exemptions and discounts on fees or public prices for urban and interurban public transport and for access to social, cultural, sports and leisure goods and services (Article 7).
• Priority access to measures for shared responsibility in childcare, and special protection for single mothers who are victims of gender-based or sexual violence. Single mothers with a minor child with grade III dependency will be considered a group of special vulnerability (Article 2).

What the royal decree-law does not say is how much each discount will be or which specific discounts each autonomous community or city council will offer. That will depend on the rules approved by each public authority. In the meantime, be wary of any figure that is not backed by a published rule.

If you are an employee, bear in mind that work leave has its own rules: for example, birth leave in single-parent families or the reduction of working hours to care for children have their own rules.

Maintenance Payment Guarantee Fund: What Is Extended

The second chapter of the royal decree-law returns to the Maintenance Payment Guarantee Fund, which advances part of the child maintenance when the other parent does not pay. If you want to know how it works today, see our guide to the Maintenance Payment Guarantee Fund in 2026. The changes in this royal decree-law are these:

• Adult children with a disability or dependency: the Fund also covers adult children with a disability rating of at least 65% or with a recognized dependency. The disability or dependency is proven with the resolution or certificate of IMSERSO or the competent body of the autonomous community.
• Urgent procedure: it can be requested when the family unit’s resources do not exceed half of the Fund’s income limit, or when the applicant is a victim of gender-based violence. In that procedure it is enough to prove that enforcement of the judgment that recognized the maintenance has been requested in court.
• Deadlines: the authority must decide within three months in the ordinary procedure and within two months in the urgent procedure. If it does not notify a decision in time, the application can be deemed granted, without prejudice to its obligation to decide.
• Requirement that remains: the judgment recognizing the maintenance must have been issued by the Spanish courts.

In addition, Article 8 provides that the advances cover unpaid maintenance until the child comes of age, in the amount and for the duration set by regulation.

Foreign Families Living in Spain

Many single-parent families living in Spain are foreign, and the question is a natural one: will they be able to request the certificate? The royal decree-law does not include a nationality requirement for single-parent families. For what it does not expressly regulate regarding recognition of the certificate, it refers, on a supplementary basis, to Title I of Law 40/2003 on Large Families.

And that law, in its Article 3.2, recognizes large family status for families from other countries on equal terms with Spanish nationals, provided that all members giving entitlement to the benefits are resident in Spain, under the terms of Organic Law 4/2000 on foreigners (Ley de extranjería).

That is why, if you are a foreign national, keeping your residence permit and your children’s up to date will be key. How each autonomous community will apply this reference when issuing the single-parent family certificate remains to be seen.

What You Can Do Now Until January 1, 2027

Although the certificate cannot be requested yet, you can get ahead:

• Check whether you fit any of the cases in Article 1, especially if there are two parents (sole custody without child maintenance, gender-based violence or forced absence of one year or more).
• Gather the documents likely to prove your situation: family book (libro de familia) or birth certificates, custody judgment or agreement, disability or incapacity resolutions, and proof of the family’s and the children’s income.
• If you are already a large family with three children and low income, prepare the documents to request reclassification to the special category.
• If your children are studying and are between 21 and 26, keep their enrollment records: the certificate’s validity may depend on them.
• Watch your autonomous community: it will publish the procedure and the application form.
