Modifying Divorce Measures: When and How to Request Changes

The measures adopted in a divorce judgment are not immutable. Life changes, circumstances evolve, and Spanish law provides a specific mechanism to adapt measures to the new reality: the modification of measures regulated in Article 775 of the Civil Procedure Law (LEC). This article provides an in-depth analysis of when modification can be requested, what requirements must be met, which measures can be modified, and how the procedure works.

Legal Foundation: Article 775 LEC

Article 775 LEC establishes:

"The Public Prosecutor, when there are minor or incapacitated children, and in any case the spouses, may request from the court the modification of measures agreed by the spouses or adopted in the absence of agreement, provided that the circumstances taken into account when approving or granting them have substantially changed."

Three fundamental elements are extracted from this provisión:

Standing: spouses always; the Public Prosecutor when minor children or persons with judicially supplemented capacity exist.
Scope: both regulatory agreement measures (mutual consent) and court-imposed measures (contested) may be modified.
Essential requirement: substantial change in the circumstances that were considered when adopting them.

The Key Concept: Substantial Change of Circumstances

The Supreme Court has detailed what constitutes a substantial change. Not every change justifies modification; it must meet these characteristics:

Case Law Requirements (STS 43/2015, February 17)

Supervening: the facts must be subsequent to the judgment or agreement. Pre-existing circumstances that were not alleged do not constitute substantial change.
Relevant: the change must have sufficient significance to alter the factual basis on which measures were adopted.
Permanent or stable: merely circumstantial or temporary changes do not justify modification. Temporary unemployment does not automatically equate to substantial change if prompt reemployment is expected.
Not voluntarily provoked: the person required to pay cannot artificially cause an income reduction to request pensión reduction. Article 152.5 CC requires that the need arise from non-culpable conduct.
Proven: documentary evidence is required. Mere allegation is not sufficient.

Measures That Can Be Modified

1. Child Support

This is the most commonly requested modification. Both reduction and increase of child support may be requested.

Common grounds for reduction:

Involuntary job loss by the support payer (dismissal, collective redundancy, employer insolvency).
Substantial income reduction (position change, working hours reduction for objective reasons).
Birth of new children of the paying parent (increased family burden).
Adult child's access to their own income (employment, scholarship).
Serious illness or supervening disability of the payer.

Common grounds for increase:

Increased needs of the minor (special education, medical treatment, educational activities).
Substantial improvement in the payer's income.
Cost of living increase not compensated by the agreed CPI adjustment.

Important: The Supreme Court (STS 599/2015, November 3) has indicated that child support for minors has a preferential and proportional character, and its reduction is only appropriate when the impossibility or serious difficulty of maintaining the amount is effectively proven.

2. Custody Regime

Custody may be modified from sole to shared (or vice versa) and the custodial parent may change. Common grounds:

Children's increased age: the passage of time and children's maturity may make a regime suitable for babies or young children no longer appropriate for adolescents.

Change of residence by the custodial parent: especially if it involves relocation to another city or country, hindering the visitation regime.
Repeated breach by the custodial parent of obligations (preventing visits, neglecting the minor, parental alienation).
Minor's wish: from age 12, minors must be heard and their opinion weighed (Art. 92.6 CC, Art. 9 OL 1/1996).
Case law evolution: as mentioned, the trend toward shared custody as the preferred regime may itself constitute a change in circumstances (STS 758/2013).

3. Use of the Family Home

Article 96 CC regulates the assignment of use of the family home, granted to the spouse with whom minor children remain. This assignment may be modified when:

Children reach majority or become independent.
The custody regime changes (from sole to shared).
The spouse assigned use forms a new family unit or cohabits with another person.
It is proven the assigned spouse can access alternative housing.

The Supreme Court (STS 641/2018, November 20) has clarified that home assignment in shared custody must consider criteria such as the interest most in need of protection, with alternation of parents in the home not being automatic.

4. Compensatory Pensión

The compensatory pensión (Art. 97 CC) may be modified or extinguished:

Modification due to changed circumstances: economic improvement of the recipient, worsening of the payer's situation.

Extinction due to marital cohabitation of the recipient with another person (Art. 101 CC): "The right to the pensión is extinguished by... living maritally with another person."
Extinction due to cessation of cause: if the economic imbalance disappears.
Temporal extinction: completion of the period set in the judgment.

5. Visitation Regime

The visitation and communication regime with the non-custodial parent may be expanded or restricted based on:

Changes in children's age and needs.
Changes in work or geographic circumstances.
Conflict during exchanges.
Risk situations for the minor.

Modification Procedure

If both ex-spouses agree on the modification, they may submit a new regulatory agreement to the court that issued the divorce judgment. The procedure is simple and quick:

Drafting the new agreement with modified measures.
Filing the mutual consent petition with the agreement.
Ratification by both parties before the Judge.
Judicial approval (unless prejudicial to minor children).

Estimated timeline: 1-3 months.

Contested Path

When there is no agreement, the procedure is contested:

Modification petition (Art. 775 LEC): must identify the measures to be modified, allege and prove the substantial change of circumstances, and propose new measures.

Admission and service: the court admits the petition and serves the other spouse, who has 20 days to respond.
Oral hearing: appearance before the judge with evidence (documentary, witness, expert, exploration of minors if appropriate).
Public Prosecutor intervention: mandatory when minor children exist.
Judgment: the judge decides whether modification is appropriate and, if so, sets the new measures.
Appeal: to the Provincial Court, within 20 days.

Estimated timeline: 6-12 months.

Provisional Measures in Modification

Article 775.3 LEC allows requesting provisional measures in modification proceedings. This is especially relevant when the situation requires immediate action (e.g., job loss with inability to pay the set support, or urgent custody change due to risk).

Common Scenarios and How to Address Them

Scenario 1: Job Loss

Juan was dismissed from his company after a collective redundancy. His child support is €500/month for two minor children. Can he request a reduction?

Yes, if he proves:

Registration as a job seeker with active search
The dismissal was neither voluntary nor provoked
He has no other income or assets allowing maintenance of the support
The situation extends over time (not temporary)

Caution: the judge will assess the payer's overall assets. If he has property, savings, or other resources, the court may determine he can temporarily maintain the support.

Scenario 2: Adult Child's Independence

María pays €400/month in child support for her daughter, who has just turned 18 and started full-time work earning €1,200/month.

She may request extinction of the support obligation. Article 152.3 CC establishes that the support obligation ceases when the recipient can practice a trade, profession, or industry. The Supreme Court (STS 700/2014, November 24) has clarified that reaching majority does not automatically extinguish the support but does allow reexamination of whether the need persists.

Scenario 3: Custodial Parent's Relocation

Carlos has sole custody and announces he is relocating with the children to another autonomous community for work reasons. The mother requests custody modification.

The Supreme Court (STS 642/2012, October 26) has established that the custodial parent's relocation constitutes a substantial change of circumstances that may justify custody review, especially if it seriously hinders the other parent's visitation regime.

Scenario 4: Compensatory Pensión Recipient's Cohabitation

Ana receives a compensatory pensión of €600/month. Her ex-husband discovers she has been living with a new partner for a year.

He may request extinction under Article 101 CC. Marital cohabitation (more uxorio) is a legal cause of compensatory pensión extinction, regardless of whether the recipient's new partner has income.

Necessary Evidence

The burden of proof falls on the party requesting modification. The most relevant evidence includes:

Documentary: payslips, income tax returns, tax authority certificates, unemployment benefits, property deeds, rental contracts.

Witness: persons who can attest to the changed circumstances.
Expert: private detective report (marital cohabitation), psychosocial report (custody change), economic assessment (assets, ability to pay).
Minor exploration: when custody or visitation regime changes are requested.
