First of all, timing is important, here. If you pass away, your son inherits your money and deposits it into joint marital accounts, then there is a good chance that your DIL can claim this. If you are alive and your son has not inherited the money, then she has no claim. If you are deceased but your son has not claimed his inheritance, then your DIL is quite likely out of luck.
There are a number of ways of protecting your son from a divorcing spouse. One good method is by setting up a trust. The trustee would have the discretion to either pay money out or to hold it in trust until any divorce proceedings are concluded. Your DIL cannot claim anything that your son does not have access to.
Whatever you set up should be done by a lawyer. Your lawyer can deal not only with this issue, but anything else that needs to be taken care of to protect you and/or your son.

If I refer to your state's laws, you should not rely on what I say; I just did a quick Internet search and found something that looked relevant that I hoped you would find helpful. You should verify and confirm any information provided with an attorney licensed in your state.
It depends what happens first and how your son treats the inheritance. If he gets divorced first, then she would have no rights to any future inheritance. If you were to die first, your son needs to make sure that he keeps any inheritance in a separate account with just his name and doesnt combine it with marital assets. Again your daughter in law wouldnt be able to get the funds. Depending on the size of your estate, you may want to do things to avoid probate including setting up a Trust and not distributing funds outright to your son to again protect the funds from your daughter in law. If I can help or answer any other questions, please contact me. Ken
As the other attorneys have indicated, timing matters. If you are still alive when they divorce, then the soon-to-be-ex will not be able to get any of your estate. Even if that is not the case, a well-crafted estate plan can help ensure that your assets are distributed according to your wishes, including protecting them from claims made by your DIL.

The first question asked in a divorce is whether something is a marital asset. Money not yet received, or money that has always been kept in a separate account will generally not be a marital asset. You should talk to a lawyer who has experience with estate planning in a setting where a potential heir is facing the possibility of divorce. The lawyer can suggest ways, such as a trust, that can keep the assets out of the marital estate. Call me at 810-664-1388 if you would like to discuss this further.
