Three axes: the bond, the children and the assets.
Almost every family matter combines three questions: what the bond is (marriage or stable union, existing or ended), whether there are children (custody, parenting time and support follow their own logic and rarely end with the couple) and what happens to the assets (the property regime defines what is divided — and what is not).
The order in which these questions are resolved changes the cost and the toll. A prenuptial agreement made in time avoids the division dispute years later; a well-written custody agreement avoids a judicial visitation ruling. When the conflict already exists, each service page explains the path — and the limits of what the law allows.

Meet Letícia MarquesQuestions about family law.
When does it make sense to see a family lawyer?
Before the crisis, when possible: a prenuptial agreement and a cohabitation contract are organized before the marriage or the union. After it, when the conflict involves custody, parenting time, child support or asset division, early guidance prevents improvised decisions that are hard to reverse later.
Can family matters be resolved at a notary, without a lawsuit?
Partly. A consensual divorce with no minor or incapacitated children is done by public deed (CPC, art. 733), recognition of a stable union and the prenuptial agreement are drawn at the notary, and voluntary paternity recognition is done at the civil registry. Custody, visitation and child support for incapacitated children, however, require a judicial resolution.
Does the firm work with mediation and settlement?
Yes. The Code of Civil Procedure encourages consensual dispute resolution (arts. 3, §3, and 694), and in family matters a well-designed settlement usually preserves the future relationship between parents. When consensus does not exist or there is urgency — unpaid support, disputed custody — the judicial route remains available.
How much does a family lawyer cost in São Paulo?
It depends on the service: a prenuptial deed, a consensual dissolution, a child support action and a custody dispute require different work. Fees are agreed in writing before any step, observing the parameters of the OAB/SP Fee Schedule; court costs, notary fees and evidence expenses are itemized separately.
Do you serve clients outside São Paulo or abroad?
Yes. Family jurisdiction generally follows the domicile of the parties or the child, but we conduct cases remotely with correspondents under our direction when an act requires physical presence. Matters with a link to another country are covered on the international family law page.
