2. What is legal notice? Can I send it myself or should I ask a lawyer to do that? What time period is an acceptable time period to ask for to return the money? What would be typical cost of sending legal notice?
You may consult a local lawyer with the evidences in your possession and seek his advise about proceeding with issuing a legal notice in this regard, sh shall guide you about it and also he may notify you the lawyer's fee for sending the legal notice.
The property was bought by my money 100% (I can prove it with documents as I was employed and she was not working at that time) but I bought it on wife's name. The reason I bought it on my wife's name was that I bought it so that parents of my wife can live in that property (so you can see I have been cheated royally) and they were only comfortable with living in a property in their daughter's name. I did the whole thing based on trust in 2007. When we sold this property in October 2016, as my wife was the only seller, she could have deposited the proceeds in her individual account or joint account. So when she deposited the proceeds into joint account, in a way, she is agreeing that the proceeds belongs to both of us (as the money to buy this property came 100% from my salary). Later she changed her mind and did this act and thats what I am trying to position as act of misappropriation. Am I thinking in the right direction?
The above reasoning may be logical and justified stand from your side, but the maintainability of the case wold not depend on this logical reasons because the pr operty though funded fully by you, it was bought on her name hence it becomes her own and absolute property and the sale proceeds from the disposal of the property hall be her own wealth and income.
Therefore your explanation or argument may not stand a ground to justify your claim.Law is above sentimental feelings.
I assume that if she does not return the money (50%) after sending legal notice, civil lawsuit can be filed. Generally how much time it takes to get a decision on this kind of civil lawsuit? What is the time limit in which one must file civil lawsuit?
The money recovery suit will take at least few yeas to get disposed.
The limitation for filing a money recovery suit is 3 years
