About Greatrix Law
Greatrix Law is a Guelph firm built around family law and divorce. It acts for individuals and families as they work through separation, divorce and family law disputes, and it brings close to two decades of family law experience to that work. Clients can also turn to the firm for wills, powers of attorney for property and personal care, and probate planning and estate administration.
Sarah A. Greatrix is the principal lawyer, with a practice that centres on family and divorce law, wills and estates, and mediation. Sarah grew up in Eastern Ontario, moved to Kitchener-Waterloo for an honours psychology degree at the University of Waterloo with a specialization in sexuality, marriage and family issues, and then earned a Bachelor of Laws at the University of Windsor in 2007.
Associate lawyer Vanessa Wotten works with individuals and families on divorce, parenting arrangements, child and spousal support, and separation agreements. Vanessa finished a J.D. at Windsor Law in 2024 and articled with a mid-size Waterloo firm. Terresa Janssen, the senior law clerk, has more than twenty years in family law and is the person new clients usually speak with first.
Plenty of family files can be settled without a fight, but Greatrix Law is ready to litigate when one can't. Sarah has argued motions and taken part in trials in both the Ontario Court of Justice and the Superior Court of Justice. Meetings happen in person or virtually, and a one-hour consultation costs $300, HST included. (Fees as of October 2026.)

Marriage contracts and cohabitation agreements
The firm drafts customized prenuptial agreements. Sarah Greatrix has a particular interest in negotiating and preparing complex cohabitation agreements and marriage contracts.
Support and property
On spousal support, the firm can pursue a claim against a former spouse or partner, or negotiate support for a client. Its lawyers also deal with property issues for married spouses and for common-law couples.
Family violence
Clients dealing with family or intimate partner violence can talk through their situation in a safe, confidential setting. In these cases the office has sought custody arrangements and claimed exclusive possession of the home, with the safety of clients and their children as the priority.
Settling outside court
For families who'd rather not litigate, Greatrix Law supports settlement meetings, mediation, arbitration, mediation/arbitration, collaborative law and negotiation, and stays with the client through whichever route they choose.
Wills and estate administration
Besides preparing wills and powers of attorney, the firm works on estate administration and walks executors through the whole process, even when an estate ends up in a dispute or in litigation.
