Compassionate Family Legal Counsel in Oak Park, Illinois

Serving clients throughout Oak Park, River Forest, and the Chicagoland metropolitan area, Conniff and Keleher, LLC is dedicated to helping families navigate life-changing domestic transitions. Established by managing partner Lyn C. Conniff and equity partner James T. Keleher, the firm brings together more than seven decades of combined legal proficiency. Family conflicts require a delicate balance of assertive advocacy and emotional intelligence. When individuals need to find an attorney to protect parental rights or hire a lawyer to preserve hard-earned assets during a high-conflict separation, the team delivers clear guidance, creative dispute resolution, and steadfast courtroom representation.

Strategic Advocacy from Skilled Divorce Lawyers

Navigating a marital dissolution involves critical financial and emotional decisions. Serving as dedicated divorce lawyers, the firm guides clients through every phase of contested and uncontested divorce proceedings. The attorneys emphasize collaborative law and constructive negotiation to minimize conflict, yet remain fully prepared to litigate complex disputes involving business valuations, retirement division, executive compensation, and maintenance determinations.

Protecting Parental Rights with Child Custody Lawyers and Child Support Lawyers

The well-being of your children remains the highest priority in any family law dispute. As trusted child custody lawyers and child support lawyers, the attorneys assist parents with:

  • Allocation of parental responsibilities: Formulating comprehensive parenting plans that detail decision-making authority for education, healthcare, and extracurricular activities.
  • Parenting time schedules: Establishing practical weekday, weekend, and holiday schedules that prioritize the best interests of the child.
  • Child support calculations: Determining support obligations under the Illinois income shares model and handling modifications when income changes.
  • Parentage and paternity actions: Establishing legal parentage for unmarried couples to secure parental rights, visitation, and financial contributions.

Marital Agreements, Adoption, and Protective Orders

Beyond divorce, the firm provides forward-looking legal services to safeguard relationships and personal safety. As experienced prenuptial agreement lawyers, the firm drafts clear premarital and postnuptial contracts to define property expectations and protect family businesses. In addition, the firm assists families with stepparent adoptions and acts swiftly when individuals need a lawyer urgently to secure orders of protection through skilled domestic violence lawyers.
