Applying for the supplementary allowance for children with a disability

The special supplementary allowance is a financial aid to compensate for the additional expenses caused by the child's disability.

This monthly benefit is granted in addition to the family allowance.

Applications for the special supplementary allowance must be submitted to the Children's Future Fund (Caisse pour l’avenir des enfants - CAE).

Who is concerned

The supplementary allowance is paid for children already receiving family benefits, and who suffer from one or more conditions resulting in a permanent deficiency or loss of at least 50 % of their physical or mental capacity in comparison to a child without disability of the same age.

The allowance is paid until the child turns 18, but the cut-off age may be extended to 25 included, provided that the disabled young person continues to satisfy the qualifying conditions for maintaining the family benefit.


In order to be able to claim the special supplementary allowance, a physician must first certify that the disability rate is at least 50 % of the physical or mental capacity of a child without disability of the same age.

The special supplementary allowance is paid for as long as the conditions for granting the family benefit are satisfied.

How to proceed

Submitting the application for the supplementary allowance

To receive the special allowance, the following must be sent to the Children's Future Fund:

  • a special supplementary allowance application form; and
  • a recent detailed medical certificate.

The application form for the special supplementary allowance must be applied for in writing to the CAE by using the form provided for this purpose on the website of the CAE.

The CAE may request additional documents to complete the application. These documents can be sent :
  • by post; or
  • via
The social security's examining physician will determine the disability rate either by calling in the person for an examination, or on the basis of their file. Their assessment may differ from that of the child's GP (general practitioner). The CAE is bound by this opinion and may only grant the allowance if the disability rate is confirmed by the social security's examining physician.

Amount of allowance and payment

The amount of the special supplementary allowance is EUR 200 per month.

If applied for in a timely fashion (end of the month for which it is due), payment of the supplement will commence in the month following that in which the reduced capacity of the child reaches or exceeds 50 %.

The allowance is paid in the same conditions as the family benefit.


Any decision in connection with the benefits may be challenged before the Chairman of the Management Committee of the Children's Future Fund or their delegate.

Decisions are considered final if the beneficiary does not send a written, substantiated objection to the CAE Management Committee within 40 days.

The decisions of the CAE Management Committee may themselves be challenged before the Social Security Arbitration Tribunal (Conseil arbitral de la sécurité sociale), and appealed before the High Council of Social Security (Conseil supérieur de la sécurité sociale).
