My sister and me wanted to buy a Apt flat but since loan can't be taken if flat was co-owned by both brother and sister so i got the flat registered on my sister name and she took the home loan. As for my share, i payed by personal loan. Now she got married and small quarrels have started. Before anything goes big, i want to safe-guard my share by some agreement so she can't sell the property with out my consent and to furnish i am half owner. Please suggest what agreement i need (any sample format is appreciated).
