Many couples in second marriages sign a marriage agreement, or prenup, saying each will keep their own property and won’t claim against the other’s estate. When one dies and the will follows the agreement, the survivor may still want to bring a wills variation claim. In BC, the agreement doesn’t prevent the claim: courts have long held that it’s against public policy to contract out of the court’s power to vary a will. But the agreement is an important factor in deciding what’s adequate. Courts generally respect an agreement that was negotiated with independent legal advice and that met each spouse’s family law obligations. Where circumstances changed in ways the agreement didn’t anticipate, such as decades more of marriage, illness or care given, the court may give it less weight. Children of the will-maker aren’t bound by their parent’s agreement.<\/p>\n

Lawgical Law Corporation<\/a>, a probate and estate litigation law firm with offices in Surrey<\/a>, Abbotsford<\/a> and Vancouver, BC, acts for surviving spouses and for estates in wills variation claims involving marriage and separation agreements; this guide is by Sundeep S. Grewal.<\/p>\n

The rule<\/h2>\n

Marriage and separation agreements that say a spouse gives up WESA rights don’t oust the court’s jurisdiction, because parties can’t contract out of socially remedial legislation (Re McNamara<\/em>, 1943 CanLII 397 (BC CA)). The agreement remains a relevant circumstance in deciding whether the will is adequate (Chutter v. Chutter Estate<\/em>, 1999 CanLII 5807 (BC SC), affirmed 2000 BCCA 205).<\/p>\n

The Court of Appeal has confirmed a prenuptial agreement is a factor in deciding whether the moral obligation to a spouse was met (Howard v. Howard Estate<\/em>, 1997 CanLII 3553 (BC CA)). The Supreme Court of Canada has said courts should be reluctant to interfere with an agreement the parties reasonably relied on, if it’s substantively fair (Hartshorne v. Hartshorne<\/em>, 2004 SCC 22), though BC courts have found that decision of limited help in wills variation (Steernberg v. Steernberg Estate<\/em>, 2006 BCSC 1672).<\/p>\n

What about the children?<\/h2>\n

An agreement between spouses doesn’t take away the will-maker’s children’s own right to bring a wills variation claim.<\/p>\n

If you were separated when your spouse died<\/h2>\n

A separated spouse may have lost spousal status for wills variation. See separated spouses and wills variation<\/a>.<\/p>\n
