Waiving debts in one’s will

If a man records in his will that any debts owed to him are waived upon his demise, this will be valid and will fall under the category of a bequest (Wasiyyah) which will be limited to one-third of the estate.

Therefore, in the enquired case, the bequest recorded by your father in his will is valid and his heirs are bound to honour his bequest to waive any debts owed to him up to one-third of the estate.

However, if there are remaining debts above one-third of the estate, the heirs have the right to claim them.

In such situations, a competent Aalim should be consulted to advise and guide the heirs.

And Allah Ta’ala Knows Best
