Must a Catholic married couple own all things in common? I know the sacrament is supposed to make two people 'one flesh', but increasingly these days couples who marry later tend to bring a lot of personal posessions to the marital home. Is everything necessarily in common? Bank accounts? Savings and investments?
certainly if there is a good reason for it, to protect assets of one from liability exposure incurred by the other, if either is a sole proprietor of a business, or in charge of an account, trust, investment for other family members. There may be good and beneficial reasons for filing separate tax returns, and separate accounts for the same reasons. The difference is setting these arrangements up for the good of both parties and the family in general. For instance a spouse who travels a lot for business might want to have a credit card in his name just for those expenses to make business and tax accounting easier. If either party is setting up such an arrangment for the purpose of safeguarding assets in case of divorce, that is anticipating divorce even expecting it, and could and probably would invalidate the marriage. For instance older persons who remarry might have accounts jointly with a child from the previous marriage, or accounts in their own name which name a child as beneficiary, as part of estate planning.
even a pre-nup does not by definition invalidate a marriage, it may be required for instance under the terms of ownership of a family business or trust for instance, but if its purpose is primarily in anticipation of divorce, that could invalidate the marriage.
