People treat “we never got married” as a force field.
It is not. In a lot of places, a long girlfriend or boyfriend arrangement starts to look like a marriage the moment money, housing, and time have been mixed. Sometimes the law names it. Sometimes it does not, and you still get a claim dressed up as a constructive trust, an implied partnership, unjust enrichment, or “I helped you build that.” The label is a local problem. The pattern is not.
If you share a life and you never wrote down what that meant for the company, you already have an unofficial marriage. You just skipped the part where both of you admitted it.
Unofficial is not the same as unprotected
Marriage at least comes with a known process, even if it is a bad one. Informal relationships come with vibes.
One person thinks this is a five-year chapter. The other thinks this is the rest of their life and the company is “ours” because they lived through the years it grew. Neither of you is lying. You just never made the terms explicit, so each of you filled in the blanks with whatever made you feel safe.
That is how you get lies, surprises, and the particular disbelief that the other person could act that way. The behaviour was often visible for years. Love is very good at refusing to connect dots.
Set expectations in writing while it is still a conversation, not a claim. If you will not marry, say so. If the company is not jointly owned, say so. If the home is yours and the other person is living in it, say so. Silence is not neutrality. Silence is whoever has the more aggressive story later.
The wealth-trap, unmarried edition
The same trap as a missing prenup, with worse paperwork.
You are not wealthy yet, in cash or in assets, so you tell yourself there is nothing to protect. Then the company works. The person who was there for the ugly years feels entitled to a share of the pie they sat through. They may have no shares, no directorship, no salary history that matches the story they will tell. They have time, proximity, and a narrative. Narratives do well in rooms where nobody can see the cap table.
Do not wait until you are wealthy to have the conversation. That is when it stops being a conversation.
This is not a speech about distrust. It is the same peace-of-mind point as a prenup. Both of you know how this works if it ends. If it never ends, the document sat in a drawer and cost you a week. If it ends, you do not get to discover the terms in a letter from someone you used to sleep next to.
Mixing is the mechanism
The failure is rarely a single dramatic transfer. It is mixing.
Salary from the operating company into a joint account. The other person on a lease they do not pay. A “temporary” director title for a bank. Personal guarantees. A card they use for groceries that is on the company. A house deposit from a holding that was supposed to stay clean. None of these look like a wedding. All of them look like contribution when a lawyer reconstructs the last five years.
Holdings, operating companies, and personal accounts fail in the same way they fail inside a marriage: the value is reachable, and the story of who created it is messier than you think. Hiding the value in a shell because you are nervous is not a plan. It is discovery bait, and in most places it is illegal. Everything we do is above board. If a move only works when nobody finds it, it is not a move we will make.
What an agreement does when there is no marriage
You can still write the operating manual.
Who owns what. What happens to the home. What happens to the company. What is a gift, what is a loan, what is compensation. What is not jointly built just because someone was in the building. Both sides get consideration, or it will not hold. Keep it simple. Do not write a novel of grievances.
Detach the couple, or the almost-couple, from the negotiation. One representative each. You stay in the relationship. They argue the terms. That is the same service we run for people who are actually getting married. The legal instrument changes with the facts. The process does not.
JSVHQ is not your family lawyer. We will not file a cohabitation contract and call it a day. We map the companies and the cash, we brief counsel who will draft, and we stop the personal side and the corporate side from contradicting each other. If you want a name: this still sits inside the Marriage Safeguard Policy. The policy is not a wedding product. It is a process for people whose lives and companies have already mixed, or are about to.
Second relationships make this worse, not better. There is often a first family, a first set of children, and a first pile of assets that was supposed to stay separate. Then a new partner moves in, contributes in ways that are real and unrecorded, and five years later everyone has a different story about what “ours” meant. The wedding you skipped does not protect the children from the first relationship. It also does not protect the new partner from being treated as a guest in a life they helped run. Write it down. Both sides. While you are still able to be fair.
We do not publish a list of countries where cohabitation equals marriage. The answer changes, and we are not your local family lawyer. Assume the mixing can be reconstructed. Assume a narrative will be built. Assume “but we were never married” is an opening line, not a defence. Then decide whether you want that reconstruction done by you, in calm, or by someone else, in heat.
The coordination problem you cannot DIY
A capable person can download a cohabitation template. That is not the job.
The job is that family counsel, corporate counsel, the bank, and the accountant each see a fragment. Your disclosure perimeter is as tight as your least-briefed adviser. One of them will say something in a letter that becomes the other side’s exhibit. Nobody owns the whole picture, so nobody can be blamed when the fragments get assembled by someone who does not like you.
That is the condition the engagement exists to resolve. Not “remember to write things down.” You already knew that. Own the map so the people drafting for you are not guessing.
For the married version of the same conversation, start with A prenup is not asset protection. For the version where a claim is already in motion, that is the Crisis Asset Protection Plan. The clock on moving value once a claim exists is the same clock as asset protection as a timeline.
If the relationship is informal and the company is real, do not wait for a wedding to take it seriously. Book a consultation. Bring the cap table and the living situation. Leave the speech about how this one is different at home.
