What state are you located in?
Texas is a community property state. Under Texas law, if you have any equity in the house, it will get divided 50-50. So, say our mortgage is 100k and your house is worth 150k, then you and your husband would both be entitled to 25k. Or, you would work out a deal that reflect that value being given to each spouse.
The same hold true for any other assets that you two acquired while married. If your dental office is opened after marriage and is worth 200k, he would be entitled to 1/2 of that. You would be entitled to half of his assets as well.
Any savings account that you opened before marriage and kept separate is your separate property.
If you opened a saving account after getting married it is considered marital property even if he did not have any income while the two of you were married. Here is the Texas law that explains the difference between community property and separate property.
If your husband rarely worked during your marriage, then that may be a basis for the court to create an unequal division of the assets. Under TX law, the court has discretion to distribute the community property in whatever way it believes is fair, but there must be a reasonable basis for a distribution that's not equal.
The court will likely ask him to offset the value of those against the value of yours so as to achieve a balance. For example, if your dentist office is worth 100k and his overseas properties are worth 100k, then you would be able to keep your dentist office and he his overseas properties.
