The answer to that question is yes she can.
it’s been said that Jennifer is going to hold possession over the eight carat ring despite them splitting their assets and moving on with their lives.
Family law specialist David Glass told People on Tuesday:
‘The engagement ring pre-dates the marriage, and therefore is Jennifer’s separate property regardless of whether it is mentioned in the prenuptial agreement,
‘As long as the parties get married, then the recipient keeps the engagement ring.’
Now that’s something you wouldn’t want to give back now would you?
