Yes, under certain circumstances. A person who personally paid the deceased's funeral expenses can claim reimbursement from the estate even if they renounce the inheritance.
The right to claim reimbursement for these expenses is separate from the right to inherit. Therefore, renouncing the inheritance does not, in itself, preclude claiming reimbursement for funeral expenses paid personally.
The person requesting reimbursement should keep invoices, receipts and proof of payment in order to establish the amounts they actually paid.
However, reimbursement is not necessarily full or immediate. It depends in particular on the financial situation of the estate and the rules applicable to the payment of its debts and expenses.
When the estate's assets are insufficient to cover all outstanding debts, the executor must adhere to the rules governing the payment of creditors. Therefore, having paid funeral expenses does not automatically entitle the executor to reimbursement before all other creditors.
It may also be useful to check if certain death-related benefits can be used to reimburse the person who paid for the funeral expenses.
