Massallah pertaining to drawing up ones will

Assalaamu Alaikum Mufti,
I’m not able to pay my wife back for her contribution to the car we bought and she also received an amount of R40,000 inheritance money a few years back which went to towards our debt. Can I make mention in my will she should be repaid from the inheritance I leave behind if there cash when I pass away?
Shukran
