Relatives stole my gold jewelry, and now I took the gold money to buy the house. He did not return me to go to the court. Evidence also had witnesses as relatives and friends and relatives.

There are two ways to have evidence and evidence chain:
This can be fully proved to theft, and the case can be reported to investigate the crime of theft.
It can only prove that things are yours. Now he possesses it. If you ask for return, he refuses to return, you can consider the crime, you can report the case or sue himself.
The criminal evidence is not sufficient, but he believes that he may only prove that these property has been possessed and punished for some reason, the prosecution requests to return and compensate for losses.
The evidence depends on whether it is really sufficient, but it is difficult to form a complete evidence chain or the solitary evidence that is only one -on -one is actually difficult to determine. The court will not support your demands
