Hi Half,
What is the actual wording of his will? For example, mine leaves my "natural children, by birth or adoption" my estate in equal shares. That means if I remarry and have stepkids, only the children from my first marriage inherit.
I would also check to see if you inherit by name ("I leave all my worldly possessions to Halfmagic") or by title ("I leave all my worldly possession to my spouse") as wills can be made either way. My first will had to be changed because my ex would have inherited everything even though we were not spouses anymore.
If he buys a house with the gf as "joint tenants with rights of survivorship" she will inherit the full property if he dies. If they buy without "JTWROS" his 50% interest in the porperty passes to his heirs. If he dies intestate (without a will) the probate court will decide who has a legal right to his estate.
If the mom dies right now (not a far probability) the mom's heirs will inherit. Most likely he will be kicked out on his ass.
Any major life change warrants a new will. An attorney can draw one up for ~$350 or less. He can do his own at legalzoom.com. I also encourage people to have "living wills" and medical directives drawn up for their doctor and kids. The chances of him becoming disabled are much greater than him dying (statistically).
