Do I need to register my will, or can I just write it myself?

In India a will does not have to be on stamp paper or registered to be valid. A will you write yourself, in plain language, signed by you and attested by two witnesses who watch you sign, is generally legally valid. Registering it with the sub-registrar is optional, but it adds a layer of proof that the will is genuine and can make it harder to challenge later, which is often worth the small effort for a founder with meaningful assets or a complicated family situation. Keep it simple, name an executor you trust, be specific about assets including equity, and revisit it after big life changes like marriage, a child, or a large secondary. The rules on validity and witnesses are specific and can change, so have a lawyer review the final draft. This is general education, not legal advice.
