French direct and indirect objects

Question

When do you use leur and lui like which is it used for?

Basically instead of verb + à + someone. It’s covered well in the linked lesson: https://french.kwiziq.com/revision/grammar/when-to-use-lui-and-leur-to-replace-specific-people-with-him-her-and-them-indirect-object-pronouns -. 
What’s a little confusing for learners is that both lui and leur have alternative functions: lui as a stress pronoun (chez lui, masculine only) and leur as a possessive plural pronoun (leur chien, their dog).  However when lui and leur are indirect object pronouns they're placed between subject and verb and usually immediately before the verb.
