Yes, it is true that a married daughter cannot be a co-applicant in a loan against a property if the loan is being taken by her mother/father.

The reason for the same is that once a daughter is married, she legally belongs to a different family and there is a greater chance of disputes being raised. Thus, unless the property is in the name of the daughter, it is not advisable for the daughter to jointly apply with her parents.

Yes, it is a bit of patriarchy, if you ask me!

However, do note that some lenders- banks as well as non-banking finance companies (NBFCs)- allow members of the in-law’s family too, to be co-applicants in a loan against property.
