Since you have mentioned your age, I understand your hesitancy in tackling the issue head on. A fight against the OC is draining enough on younger and fitter people.
Unfortunately, the law does not deal with what is morally right, only what is right in law.
Even if there was some clause inthe act for your dilemma, it’s often necessary to take legal action to enforce your rights.
A good lawyer will be your best asset, but be aware that legal action will take significantly longer than you expect; it will be costly to you since you have to pay your lawyers and experts before you are awarded costs, and there is no guarantee of success.
