Seeking Advice on Legal Obligations when Leasing a Tenant

I'm brand new to real estate & am looking to start investing in small multi-family in my local area when I graduate college in the summer of 2023. 

Before you look for a tenant, you obviously need some sort of leasing agreement. I'm assuming a lawyer needs to be involved to make sure things are done right. 

Should you use a lawyer when creating a lease agreement? What other legal obligations need to be fulfilled when you're renting out a duplex, triplex, or fourplex? 

I'd greatly appreciate any advice.
