Family Support Allowance (FSA): Separated parents

Verified 01 April 2025 - Directorate for Legal and Administrative Information (Prime Minister)

Family support allowance (FSA) is paid by the Family Allowance Fund (CAF) or the Agricultural Social Mutual Society (MSA) to a person who is raising his child alone without the help of one of his parents, subject to conditions.

In all cases, to be eligible for the BSO, you must meet all of the following conditions:

  • Living alone
  • Reside in France
  • Have at least 1 dependent child for which the other parent is no longer involved in the interview for at least 1 month or pays you support of less than €199.19

Reminder

The BSO is removed if you live as a couple.

The other parent does not pay a pension

Maintenance has been fixed

The BSO is paid to you in advance.

Maintenance must be fixed by a judgment or a divorce agreement by mutual consent filed before a notary.

Your Caf (or your MSA) has 2 ways of acting:

  • Act for you and on your behalf in order to recover the pension if the other parent does not pay it (not completely or regularly)
  • Establish a recovery procedure against the other parent to recover up to 2 years of unpaid maintenance.
The other parent cannot pay child support

The FCA (or MSA) can pay you the BSO if the other parent cannot meet their obligation maintenance (insolvency, unemployment, incarceration, RSA, etc.).

She's checking the other parent's situation. Based on the evidence gathered, it tells you whether you need to take steps to determine support.

No maintenance has been fixed

The BSO is paid to you for 4 months.

To maintain your entitlement to the BSO beyond 4e months, you must within this period:

  • if you are not in possession of any court order: take action before the family court judge of your domicile, in order to have maintenance fixed
  • if you are in possession of a court decision not fixing maintenance: bring an action for review of the court decision before the same judge.
