Information is power. Unfortunately, partners looking to divorce don't take this statement with the seriousness it deserves and end up going through a tumultuous separation process. If you have reached a point where you believe divorce is inevitable, then you need to prepare well. A divorce lawyer will help you deal with the enormity of legal logistics as well as the financial commitment that comes with the proceedings. Notably, lawyers must understand your specific needs during the initial consultation meeting.
Vets have a duty of care to treat animals to set medical standards. If a vet has injured your pet or made it ill, say during a botched surgery or because of negligent care, then you may be angry enough to do something about it.
While you may get some satisfaction from reporting the vet to the authorities, this may not give you complete closure or solve all your problems. Consulting a lawyer who specialises in pet law may help.
