Seeking recourse to the court against an unjust father

The questioner:
I ask Allah (Glorified and Exalted is He) to protect the Custodian of the Two Holy Mosques and to grant him health and well-being. Say, "Ameen." Ameen, ameen. My question to the Honorable Shaykh is: What is the ruling on seeking recourse to the court against a father if he commits injustice? Is that considered undutifulness to parents? And if one is patient with his father, does he receive reward for that? And the second question

The presenter:
First of all. A moment, Ahmad. Please, go ahead.

The questioner:
An amount of money he does not need, without the slow... Ahmad. Yes, indeed.

The Shaykh:
He is asking, not rambling on to us.

The presenter:
Do not repeat your question, keep it brief, Ahmad.

The questioner:
The first question or the second question?

The presenter:
The first question.

The questioner:
The first question: Is it permissible to go to court against one's father?

The Shaykh:
Be patient, my brother. This is not permissible. Do not complain about your father, and do not sue your father. This is not permissible. Yes.
