Are there any legal pitfalls that I should be concerned of, outside of a normal prenuptial agreement? I know that the prenuptial needs to be registered, and that for her to keep her property it needs to be prenupted away from me (it's going to be "each to their own" anyway, so mentioning the property separately is somewhat moot).

She's an indonesian woman with one underage child from previous marriage; I am not going to adopt or otherwise significantly support the child.
