After living as a tenant in Gujarat for over 14 years with an expired leave and license agreement, you are seeking advice on your rights. Your landlord has passed away, and their son is now asking you to vacate. While you've been paying rent regularly, the lack of a registered agreement means your tenancy is largely based on an oral understanding. You can request an extension, but it's not a guaranteed right, and the landlord could potentially initiate legal proceedings. Seeking an amicable settlement for a year's extension or consulting a lawyer to explore legal options like an injunction suit for a more convenient move is advisable.
