Although custody is settled by the divorce judgment, it can be regulated afresh when circumstances change (Article 183 of the Civil Code). The test is not what either parent wants but the best interests of the child. There is no time limit on the claim, and the views of a child who has reached an age of discernment are always taken.
Custody was given to you or to the other parent on the divorce. But circumstances have changed — a move, a new marriage, the child's schooling, or a failure of care.
A custody order is not res judicata: it can be regulated again as circumstances change. This article sets out when, and how.
The Basis for Varying Custody
Article 183 is clear: where new facts make it necessary — a parent remarrying, moving elsewhere, or dying — the judge takes the measures required, either of their own motion or on the application of a parent.
Under the final paragraph of Article 182, when regulating the contact between the child and the parent who does not exercise custody, the judge takes as the basis the child's interests, particularly as regards health, education and morals.
There is a single test, and every decision is made against it: the best interests of the child. Which parent is in the right, at fault, or more insistent is secondary.
Mediation is not a precondition for these proceedings; the claim goes straight to the family court.
When Is Custody Varied?
The situations that in practice lead to a variation:
- The parent with custody failing in the duty of care and supervision — absence from school, medical care not followed up, neglect
- Violence, ill-treatment or abuse of the child
- Persistent obstruction of contact — attempts to cut the child off from the other parent
- The health of the parent with custody, where they can no longer provide care
- A fundamental change in living arrangements — settling abroad, or a move that disrupts the child's education
- The child's own wishes, where they have reached an age of discernment
Remarriage or a change of address is not enough on its own: it must be shown that the fact adversely affects the child's interests.
In serious cases the question is not variation but removal of custody under Article 348, in which case a guardian is appointed or custody is given to the other parent.
| Situation | How it is treated |
|---|---|
| Neglect or abuse of the child by the parent with custody | A direct ground for variation |
| Persistent obstruction of contact | A strong ground for variation |
| The parent's health making care impossible | Weighed on the facts |
| The child's education persistently disrupted | Weighed on the facts |
| The parent with custody settling abroad | Weighed on the particular circumstances |
| The other parent simply being better off | Not sufficient on its own |
| Remarriage | Not sufficient on its own |
In practice an age of discernment is usually taken as eight and above; the child's view is an important factor but not decisive by itself.
Are the Child's Views Taken?
Under the European Convention on the Exercise of Children's Rights, to which Turkey is a party, and settled practice, the views of a child who has reached an age of discernment are taken.
That age is generally treated as eight and above, but there is no fixed threshold: the child's maturity is assessed.
The child is heard in a suitable setting at court, usually with an expert present. Their view carries weight but does not bind the court: the judge also considers whether it was given under influence.
For that reason, preparing a child for the hearing and coaching what to say backfires. Experts recognise coaching, and it is held against the parent who did it.
The Evidence
The most decisive evidence in a custody file is the expert report. A team of psychologists, educational specialists and social workers attached to the family court will:
- interview each parent separately
- interview the child
- visit the home and examine the living conditions
- consider school records and, where relevant, health records
Other evidence: school attendance and attainment records, health records and vaccination history, police records, protection orders, witness evidence, and correspondence showing that contact was obstructed.
The strongest evidence in practice is concrete and dated: contact days on which the child was not handed over, messages left unanswered, days missed at school.
What to Ask for While the Case Runs
The claim should also seek interim measures to apply during the proceedings:
- interim custody, or an interim protective measure
- contact re-regulated — with the days, times and handover place stated expressly
- an interim order preventing the child being taken abroad
- child maintenance fixed or increased
Where a contact order is breached, there is a separate route. The provisions of the Enforcement and Bankruptcy Act on the delivery of children were repealed in 2022 and the subject brought within the Child Protection Act (Act no. 5395). Orders for delivery and for contact are now carried out through the judicial support and victim services directorates.
Where an order is not complied with, the application is made to that directorate, and the coercive measures are applied within that framework.
The views of a child of discernment are taken, and experts recognise coaching — which is then held against the parent responsible. The strongest evidence is concrete and dated: contact days missed, absence from school, gaps in medical care.
Frequently Asked Questions
Can a custody order be changed?
Yes. It is not res judicata: under Article 183 it may be varied where new facts make it necessary.
What is the test?
The best interests of the child. Which parent is in the right, at fault or more insistent is secondary.
Are the child's views taken?
Yes, where the child has reached an age of discernment — usually treated as eight and above. The view carries weight but does not bind the court.
Does a new marriage change custody?
Not on its own. It must be shown that it adversely affects the child's interests.
What if the contact order is ignored?
Orders for the delivery of a child and for contact are carried out under Act no. 5395 through the judicial support and victim services directorates; the application is made there.
