Do not paint all lawyers with the same brush. No doubt there are lawyers who specialize in fleecing clients, or those who are not so conversant with the laws applicable in resolving a particular case and end up misguiding a client. However this is true of all professions.
As there are bad lawyers there are good lawyers also. So the sensible approach would be to speak to a lawyer, try to asses him as a human being and as a professional, and if satisfied then only appoint him to do the job at hand.
In the present instance, basically since the problem relates to a settlement amongst family members, the actual terms of settlement are required to be decided by the parties themselves. However it may be advisable to engage a lawyer since after the terms of settlement are agreed upon, the lawyer can bring his experience in drafting the terms of settlement in a clear and precise way so that there will not be any dispute in future.
Usually in a family settlements the rights of not only the parties who are now active are decided but also the rights of the next generation are also affected. Therefore to prevent all future disputes, I am of the opinion that the services of a lawyer should be availed of.
