No-agent deal with family member. Need lawyer or just title co?

[Austen Moore]

I'm a true newbie working on my first REI deal, buying a property in Indianapolis currently owned by my father. We are trying to save money by avoiding an agent but should I be using a lawyer in the process or is working with just a title company enough? Thought some of the experienced investors and professionals, especially @Jynell Berkshire and other Indy-based folks, might be able to provide some advice. Thanks!
