The short answer
A lawyer may decline a case for many reasons, including conflicts, capacity, or economics, and a decline is not a judgment on its merits. Clients can change lawyers at any time, though timing and costs matter.
Where it fits in your case
After a declined consultation, or when you are considering new counsel.
What to expect
Deadlines such as statutes of limitations keep running; get a second opinion promptly.
Changing counsel usually requires a substitution filing in court.
Your file should be transferred, subject to the engagement terms.
Costs. A new lawyer will need time to learn the case.
What to review
Your engagement agreement, outstanding invoices, upcoming deadlines, and the case file.
Common misconceptions
“A decline means my case is bad.” Often it reflects other factors.
“I can’t change lawyers mid-case.” You can, though the court may need to approve the substitution.
