How to eliminate wife rights on a property I am purchasing?

[Jake Johnson]

Hi. 

My wife and I married only for less than a year. 

I am about to purchase turn key property in Ohio, for the money I made before we even knew each other. 

Everything is fine, but my wife always listens and does what her mom will tell her to do. And that is my concern. In case of a divorce, mother in law will tell her to get everything from me (so she can have more storage to hoard her stuff). 

I do not have LLS set up, but I will be the only on a title and  the loan is only on my name.

So am I protected enough?

Or is there like a waiver my wife can sign? And if yes, who would provide that waiver? Title company? 

Thank you
