Legal opinion required -pls advice :
I have been lending help and assistance to a 75 year widowed lady who was made homeless .
Son threatened and intimidated her to sign to sell the property and all took their shares and son took away her share also .
She is penniless.
One son & second daughter ill treated and eldest daughter can not keep her bcos of having special child of 32 years .
Arranged her to be in old age home .
In Police station, son n eldest daughter agreed for 7k monthly . The other daughter only 3k though can afford 7k.
Can I issue a legal notice as a service oriented man to the children that if they don't take care of her old age home & medical charges , I will be compelled to file a suit for recovery of the sale proceeds of the property .
Legal Advice required 🙏🙏.
