How to handle title

[Sam Dal]

Folks - if I buy a property today (pre-marriage) with a large 30% down-payment, will this down-payment be protected in a divorce settlement 5 years down the line? After getting married in 6 months, I'll be adding my wife to the title

Or will a judge see two people on the title and simply say property belongs to both equally in spite of me being the sole contributor to the down-payment

Thanks
