About Harris Marks
A Litigation-First Approach to Personal Injury Law
Harris L. Marks, Esq. founded Marks Law Group around a straightforward principle: serious injury cases should be developed as if they may ultimately have to be proven in court.
That preparation begins early. Evidence can disappear, witnesses can become difficult to locate, physical conditions can change, and insurance companies may begin developing their defense shortly after an accident occurs.
Harris therefore focuses on identifying the evidence, responsible parties, insurance coverage, medical issues, economic losses, and future consequences of an injury before allowing an insurer’s initial evaluation to define the case.
He remains personally involved in major stages of the matters handled by Marks Law Group, including investigation, pleadings, discovery, depositions, settlement strategy, expert development, and trial preparation.

Attorney-Led Case Development
The 360° Litigation Approach
A serious personal injury case is not built from a single medical record or demand letter. It requires connecting liability evidence, defendants, insurance coverage, medical proof, financial losses, expert evidence, and litigation strategy.
Harris personally oversees the major strategic decisions involved in developing that evidence and preparing a claim to withstand challenge.
1
Investigate
Preserve photographs, video, witnesses, physical evidence, reports, records, vehicles, equipment, and other time-sensitive proof.
2
Identify
Determine every potentially responsible person, company, owner, contractor, insurer, or other source of potential recovery.
3
Document
Develop medical, economic, vocational, functional, and future-care evidence needed to establish the full extent of the loss.
4
Litigate
Use pleadings, discovery, depositions, experts, motion practice, negotiation, and trial preparation strategically.
