<div lang="en" dir="ltr" class="mw-content-ltr">
{{Q|Q21510855}} specifies that a property has an inverse property, and values for the property should have a statement with the inverse property pointing back to the original item.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
For example, {{P|P25}} has the inverse property {{P|P40}}: if the statement {{St|Q302|P25|Q345}} exists, then the inverse statement {{St|Q345|P40|Q302}} should also exist.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
If no {{P|4680}} is specified, this constraint is only checked on the main value of a statement.
This is also the only currently supported scope.
</div>

<div lang="en" dir="ltr" class="mw-content-ltr">
There are several possible ways to address a violation of this constraint:
</div>

* <span lang="en" dir="ltr" class="mw-content-ltr">The most likely case is that the inverse statement should be added to the other item, where it is missing. As there may be many such cases, a frequent approach is to do this by bot.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">It’s possible that the current item should not have the statement at all, and that the statement should be removed.</span>
* <span lang="en" dir="ltr" class="mw-content-ltr">It’s possible that the item is a rare, but legitimate exception to the constraint, and nothing should be done.</span>
