Expert writing Tips
Best practice
When writing formally, ensure that the context clearly establishes who "their" refers to, to avoid ambiguity. If the reference is unclear, rephrase for clarity.

Avoid using "their" if it's not immediately clear who or what group is being referred to. This can lead to confusion. Instead, specify the group or individuals clearly: "The students had the books in their possession" vs. "The students had the books in the library's possession".

How can I rephrase "in their possession" to sound more formal?
For a more formal tone, you could use phrases such as "in their custody", "under their control", or "under their ownership" depending on the context. Consider also the alternatives "in their keeping" or "at their disposal".
What is the difference between "in their possession" and "on their person"?
"In their possession" generally means that someone owns or controls something, while "on their person" specifically means that someone is carrying something directly on their body. For example, a weapon might be "in their possession" if it's in their house, but it's "on their person" if they're carrying it.
Is "in their possession" interchangeable with "belonging to them"?
While similar, "in their possession" often implies a temporary state or a situation where someone has control over something, whereas "belonging to them" more strongly emphasizes ownership. You can also replace it with a simple "belonging to them" depending on the context.
When should I avoid using the phrase "in their possession"?
Avoid using "in their possession" if the pronoun "their" is ambiguous or unclear. Ensure the context makes it immediately obvious who or what "their" refers to. If there is any potential for confusion, rephrase the sentence to specify the possessor directly.
