Domestic Contracts (aka Prenups) and the Business Side of Marriage
Maggie Horsburgh • April 14, 2021

Prenups…we hear about them a lot in high profile marriages and in movies and television when the wealthy heir or heiress is about to get married. The term prenup (short for prenuptial) is actually an American term. In Ontario, they are referred to as domestic contracts or marriage contracts.

While the term prenup is still used in Canada, it specifically refers to contracts signed before marriage. A domestic or marriage contract on the other hand, can be signed at any time during a marriage. In the case of common law relationships, they are referred to as cohabitation agreements.

Let’s talk a bit about prenups and why I believe they are an important consideration prior to marriage, especially if it is your second or third.

Let’s face it, when you are getting married the last thing you want to think about is what happens if it does not work out. That is the main reason most marriages don’t have a prenup in place (about 92% in fact). But the hard fact is, divorces happen about 50% of the time. In the case of first marriages, when the couple is young and just starting out, there may not be a lot that needs protecting in the event things do not work out.

However, if you are getting married for the second or third time and you are coming into the marriage with assets that you have worked hard for, a prenuptial agreement makes a lot of sense. I learned this the hard way.

After my first divorce I had to survive on my own for the first time in over 17 years. I dove into my new career as a real estate agent, bought my first home (solo), my first investment property and started working hard to forge a new life for myself.

When I decided to marry again, I had built up some significant assets, including property. I did not even consider what might happen if we split up but I soon found out. Turns out that this marriage was not one of my better decisions and upon our divorce, my ex was entitled to half of my assets – including properties I had worked so hard for. It was not fair but it is the law.

There is a business side to marriage and it is important to consider financials before entering into one. Just like discussions on children, where to live and your dreams for the future, a discussion about your finances should be done before you say “I do”. If this is something your future partner is avoiding, that could be a major red flag.

A prenup gives you some insurance in case things do not work out and can help to avoid disappointment and arguments when you have already agreed on how pre-marriage property will be dealt with.

And like any legal document, it is always important to get it reviewed by a lawyer to ensure it is fair and clearly understood by both parties.

I remember sitting in my parents' living room, watching them go about an ordinary Sunday afternoon. My mother puttering in the kitchen. My father flipping through his horse magazines. They weren't unhappy. There was a certain comfort in the life they had built together, a familiar rhythm shaped by decades of shared history. They had become experts at coexistence. The sharp edges had softened with time, but so too had some of the wonder. They moved around one another with the ease of people who knew each other's habits by heart, yet I sensed a quiet distance between them. Not conflict. Not loneliness. Just an absence of curiosity, anticipation, or connection. Life seemed less like an adventure they were experiencing together and more like a routine they had mastered. And as I sat there watching them, a question settled heavily in my chest: Is this it? Is this what we're working toward? We fall in love, get married, raise our children, build careers, pay the bills, save for retirement, and then one day find ourselves sitting across from the person we've spent a lifetime with. If the children are gone, the careers are winding down, and the responsibilities have eased, what remains? Is the goal simply to endure together? Or is there meant to be something more? The question felt disloyal at the time, maybe even selfish. After all, wasn't this exactly what my parents had worked so hard to build? But once it appeared, I couldn't shake it. That question stayed with me for years. It turns out I wasn't the only one asking it. That uncomfortable question is driving a shift in family life right now. Across North America, more couples over fifty are choosing to end long-term marriages - a phenomenon researchers call grey divorce . Its rise has forced us to rethink some long-held assumptions about marriage, aging, and what we want from the second half of life. And if you're in that season of life, there's a good chance you know at least one couple it has touched. Maybe it's touched you. For many people, the children leaving home doesn't just create empty bedrooms. It creates space to finally look at life itself. Without the distractions, responsibilities, and busyness that once held everything together, some couples find themselves facing a difficult truth: they no longer recognize the life they've built or the person sitting across from them. We're Not Who We Were at 25 Here's the thing nobody says at the wedding: people change. A lot. The person you married at 27 may be almost unrecognizable at 60, and so might you. That's not a failure. That's just life doing what life does. Many grey divorces aren't dramatic. There's no affair, no blow-up moment, no single villain. It's more of a slow drift. Two people who built a life around kids, careers, and keeping the wheels turning suddenly find themselves across the breakfast table with nothing left to manage. Realizing they don't actually know each other all that well anymore. Or worse, they know each other perfectly, and that's the problem. Retirement Breaks Things Retirement was supposed to be the reward. The destination. You grind for 35 years, you get the gold watch, and then life begins. Nobody warned us that "life beginning" requires actually knowing what kind of life you want. Particularly for men, work is identity. Its structure, purpose, status, and social life all rolled into one. When it disappears, the vacuum can be enormous. Some guys handle it beautifully and discover themselves. A lot don't. And instead of confronting that loss of purpose, it gets directed at the marriage. Suddenly, couples who used to co-exist comfortably around busy schedules are home together 24 hours a day. Routines that held a marriage together evaporate. Tension shows up in places it never did before. I've seen perfectly decent couples unravel in the first year of retirement because they had no idea who they were to each other outside of the logistics of running a family. The Unfulfilled Dream Factor This part gets me every time. I've watched many people spend their best years waiting. Waiting until the kids are grown. Waiting until retirement. Waiting until then . And then "then" arrives and there isn't enough of it left. My mother may have had a list. Things she wanted to do, places she wanted to go, parts of herself she planned to explore "someday." I imagine if she had a list, she secretly kept it on a notepad in her bedside drawer. Maybe it existed only in her mind. If there were a list of things, I don’t know if she ever did them. That haunts me more than I'd like to admit, and I think it's part of why I can't judge anyone who, at 65 or 75 or even older, decides they're done waiting. I once worked with a couple in their early 80s who were separating after 60 years of marriage. Everyone around them was shocked. I wasn't. I could see that she had one chapter left, and she was not going to spend it the same way she'd spent the rest. What struck me wasn't the separation. It was the fact that she still had dreams. I was relieved that she still had dreams. The House in the Middle Okay, here's where I put on my real estate hat, because this is where things get genuinely complicated. In Ontario, the matrimonial home is treated as a joint asset, full stop. It doesn't matter whose name is on the deed, who paid the mortgage, or how long you've lived there. It's split equally. And that's just the house. Pensions, RRSPs, investments accumulated during the marriage — all of it goes into the pot. When you add legal fees into the mix, something shifts quickly. A couple who once had a comfortable retirement plan can suddenly find themselves as two individuals trying to build separate lives on what used to support one household. The financial reality of that change is often more significant than people expect. And perhaps what makes it even more complex is timing. There is no long runway to recover. Divorce in your 30s is painful, but there are decades of earning ahead. Divorce at 65 or 70 means rebuilding on whatever time is left, with far less room for adjustment. There's also the inheritance piece, and it's awkward but worth stating: when one or both spouses move on to new relationships, estate planning gets complicated fast. Kids who thought they understood what was coming can find themselves blindsided. That resentment is real, and it's worth thinking through early. These are not abstract financial structures. They are lived realities inside families. My husband likes to describe his work in his seventies as “laying fresh pavement” every day because the runway, as he puts it, technically ended, and he is simply extending it as he goes. I think about that often when I look at this stage of life and these kinds of transitions. Some people are still building. Some are beginning again. And some are doing both at the same time. That’s what makes this stage of life so complex. Not just emotionally, but structurally, practically, financially. Everything matters more because there is less time to absorb the impact. You Have More Options Than You Think When it comes to the family home, couples have real choices. Sell and split. One spouse buys the other out. There are creative arrangements that work when both parties approach the situation practically rather than emotionally… though I won't pretend that's easy when you're grieving a 40-year marriage at the same time. What matters most is getting the right people around you early. A family lawyer who understands late-life divorce. A financial planner who can show you what both paths actually look like. And a Realtor who has seen this before and won't treat your home like just another listing. Because it isn't. Grey divorce is often hard. It can be expensive and emotional, and for many people, it reshapes what they thought their future would look like. But it can also be the beginning of something you never allowed yourself to consider before. With eyes open, good advice, and honest support, some people find their way into a life they hadn’t yet imagined. What that life looks like depends on what people are willing to imagine next.

If you’ve just separated and you’re staring down a house that needs work… whether you’re preparing to sell or settling in for the long haul, this is one of the parts nobody prepares you for.
