<prompt> Human: Title is a bit blunt, but accurate nonetheless. I, 26M and she 25F have both been in a very loving relationship for 2 blissful years. Both are still in love and the relationship is still strong, even after I. . . bestowed my eminence upon her seed. Problem: We are Canadian. This means, with the current government in place, there is no appealing financial benefit to be had in marrying this woman. Religious reasonings for marriage? Perhaps. . . but then again, the deeds already done; and her father has no capacity in forming a shotgun wedding. More importantly though, I just dont want to marry her yet.Heres Why: I am a highly motivated, ambitiously career-driven individual, focused on maintaining a stable economic environment for my child. Ive maxed out my TFSAs, actively contribute to RRSPs, dabble in stock trading with my margin account. Salary is a comfortable 75k, with potential growth. Liability is my 5 year old mortgage of 290k, which I could manageably afford alone. Financially, there should be no issues raising the child Ive always wanted! SUCCESS! Her: If a butterfly managed to hack control of a human body - it would be hers. Shes free spirited, and seemingly unbound by societies paradigms. Her financial savings are comprised by the pennies she collects, and stuffs in her shoes because; Hey, they dont make pennies anymore - so theyll totally be worth so much money in the future. I kid you not! Her life is as though gold was struck after Canada announced the retirement of the currency! There are no ambitions or drive to pursue a career of any sorts. She currently works 12 hours a week, which happily covers her expenses. I seem to cover a few of her expenses which are fully within my comfort zone. A newly introduced MLM model WF has caught her attention and sparks great fear in me. A huge benefit is that her net worth is a 0, which by todays standards is great! Regardless, her concepts of obtaining financial freedom are bunk; she makes very little money; but shell always, indefinitely be infinitely happier than I will ever be!TLDR: Shes Moving In: Again, because this is Canada - Wham, Im married after 6 months anyway Common Law. What type of prenuptial agreements can I put in place to protect my past investments, savings, RRSP, TFSAs, and equity and own my own liability. What are the steps involved? Are there other options, incase she decides to turn on me? Im fully comfortable with sharing future earnings.  <response>: rlegaladvice and rpersonalfinancecanada will probably be more useful.
