My mother aged above 80 wants to write a WILL distributing her cash, gold and silver amonst her 3 children. She has no problem about cash division. But, regarding ornaments, she likes to distribute specific items to each individual. In that case, instead of listing them in the WILL, can she attach 3 annexures for 3 children and refer them in the main WILL? She will sign the annexures also. Please clarify if it is legally valid?
