The decision is up to you, but we don’t generally recommend limiting who can be a “plus one.” Not everyone has a spouse or significant other, so allowing employees to bring whomever they want is more inclusive and inviting. They’re more likely to attend and have a good time. Not placing limits on who can be a plus one also saves you from having to define terms like “significant other” or “partner” and determining whether certain guests qualify.

That said, depending on the type of event, it could be reasonable to limit guests to those who are at least 18 or 21 years old.

If you opt to restrict who can be a guest, inform employees ahead of time and be prepared to explain your reasoning.
