Is the text 若承租人是公司，则必须提供法定代表人资料 official and correct? I asked a good friend of mine to write the following text in Chinese: if tenant is a company, it should provide the name of the representative.

She translated into: 若承租人是公司，则必须提供法定代表人资料。

Since it's based of a contract, it should be written as officially as possible. But I have a hard time analysing this text.

What does: 若承 and 则必 mean?

How are these related and how to construct a sentence with it?
The text sounds very official and formal
若 (if)
承租人 (tenant)
是 (is)
公司 (company)
则 (then)
必须 (must)
提供 (provide)
法定 (legal)
代表人 (representative)
资料 (information)

若承租人是公司，则必须提供法定代表人资料。
If the tenant is a company, then it must provide the information of the legal representative

I think 法定(legal) is not needed, since the representative is bonded by a legal agreement with the company
