The underlying leave is a one- or two-month indemnified extensionAmeli taken after the maternity, paternity and welcome or adoption leave has been fully taken, with no seniority condition. It covers parents of children born or expected from 1 January 2026, or children arriving at the home for adoption from that date, and starts within nine months of the birth or arrival, with extensions where a conventional leave was taken or the initial leave was itself extended. For children born or arriving between 1 January and 31 May 2026 the nine months run from 1 July 2026. Both parents can take it simultaneously or in turn, and a two-month leave can be split into two one-month periods.
The salarié informs the employer of the expected start date, duration and any split by lettre recommandée avec accusé de réception or hand delivery against receipt, at least one month in advance or 15 days where the leave immediately follows paternity or adoption leaveService Public, with first requests possible from 1 June 2026 for leave from 1 July 2026
Service Public. The employer can neither refuse nor postpone the leave. During the leave the contract is suspended, no other professional activity is allowed, dismissal is barred except for faute grave or impossibility of maintaining the contract on grounds other than the birth or arrival, and the period counts as effective working time for seniority. Daily allowances follow the maternity, paternity or adoption calculation within the monthly Sécurité sociale ceiling, at 70 % of salary for the first month and 60 % for the second, paid directly by the primary caisse or by the employer under subrogation. Legal basis is articles L1225-46-2 to L1225-46-7, L1225-4-5 and D1225-11-3 to D1225-11-5 of the Code du travail with the net-entreprises DSN and employer-account filing route.
For each CSN period, file the DSN signalement and deposit the PDF form on the employer account the same day, within five days of the leave start.
