Looking for a family lawyer in Newmarket? We help Newmarket and York Region families with divorce, separation agreements, parenting, support and property, and we know the Newmarket courthouse on Eagle Street.

Family cases for Newmarket and the rest of York Region are heard at the Newmarket Courthouse, 50 Eagle Street West. Only the Superior Court of Justice can grant a divorce or divide property. Some parenting and support cases can also be heard by the Ontario Court of Justice in the same building. Your lawyer will tell you which court fits your case.
Most families settle through negotiation, mediation or a separation agreement. When a court case is needed, it usually moves through these stages.

Child support in OntarioEqualization of net family property, the matrimonial home, pensions and business interests.
The matrimonial homeWhen the other parent does not pay support or follow a parenting order, there are steps to enforce it.
Support enforcementIn Ontario, the usual ground for divorce is living separate and apart for at least one year. You do not have to wait to start: parenting, support and property can be settled right away, and the divorce itself follows once the year has passed. You can be separated while living in the same house.
If you are married, both spouses have an equal right to live in the matrimonial home, whoever is on title, until an agreement or court order says otherwise. Neither spouse can sell or mortgage it without the other's consent or a court order. Its value is shared through equalization of net family property, and a matrimonial home owned before the marriage is generally not deducted the way other pre-marriage assets are.
The usual options are a buyout, a sale, or a delayed sale while children finish school. Equalization claims have time limits, so get advice early. If you are not married, different rules apply; see common-law property rights.
An order or agreement only helps if it is followed. These problems come up often in York Region files:
Commuting is also a factor for many Newmarket families. A schedule that works when both parents live in Newmarket may not work when one parent moves to Toronto or Barrie, so build exchange times and locations into the plan.
Ontario law now uses "decision-making responsibility" and "parenting time" instead of custody and access. Every decision is based on the child's best interests. If one parent wants to move with the children, the relocation rules require at least 60 days' written notice, and the other parent can object. Read our child custody guide.
Child support is calculated under the Child Support Guidelines, mainly from the paying parent's income and the parenting schedule. If each parent has the children at least 40% of the time, the calculation changes; see the 40% rule.
If you are in danger, call 911.
Fees depend on how much work your case needs, and agreement is almost always cheaper than litigation. These are the three broad paths, from least to most work.
A consultation, or reviewing a separation agreement before you sign, including independent legal advice.
Disclosure, negotiation or mediation, and a signed separation agreement or a joint or uncontested divorce.
Court applications, conferences and motions, and possibly a trial, when the issues cannot be settled.
Court fees for a divorce were about $669 at the time of writing. See our 2026 family lawyer cost guide, and ask about payment plans or help with specific steps only.
Our goal for every client is simple: honest advice, a clear plan and a fair, lasting result, with regular updates on your case along the way.
