If you or your spouse anticipate future property or other financial transactions, it would be wise to record a Memorandum of Separation Agreement with the Register of Deeds office. Some lenders may want proof that an agreement has been entered into. A Memorandum allows you to show that proof without making the terms of your Separation Agreement part of the public record.
Regarding the incorporation issue, you should consult an attorney. Incorporation affects the modifiability of custody, alimony, and/or property provisions of your separation agreement.
