My wife and I are separated but not divorced. I purchased a property and registered it in her name. We’re now facing some disagreements, and she wants to sell the property. Is there a way I can prevent her from selling it, considering we are still legally married?

Since you are legally married, your wife is considered a co-owner of the property even though it is registered in her name. You have a right to the property and can file a legal suit to prevent its sale or claim your share of the proceeds if sold. However, the specific legal recourse available depends on the nature of the disagreements and the terms of any agreements you may have.
