A person co-applied for a housing loan with their father to build a first floor on the family property, and is now paying the EMI and renovation costs. Their sisters are requesting their share of the father's property. The discussion seeks advice on how to draft a will to distribute the property amongst the siblings, considering the EMI payer's contributions and potential future issues when selling the property. It also questions the necessity of a will if the property is self-acquired and intended for equal division among all children.
