Lucas is a popular name, and since it ends with an S, it can be tricky to make it possessive. Whether you use Lucas’s or Lucas’ depends on the style guide that you follow. Both Lucas’s or Lucas’ are correct.
There are several different style guides for writing the English language. When you follow the rules of The Associated Press Stylebook, Lucas’ is correct. With all other style guides, Lucas’s is correct.
The Associated Press Stylebook has rules that state any plural noun, including names that end with an S, only get an apostrophe to symbolize possession. If you are required to follow AP style in your writing, this is the correct way.
In school, we are taught that Lucas’ is the proper way to write about something that belongs to Lucas. However, language is always developing and making changes, which is why this form isn’t used as often as it used to be.

Which is Correct?
The confusion of these two words comes from what we were taught to write versus how we say things. In school, it is common to be taught to write Lucas’ when talking about something that belongs to Lucas. When we are talking, we say Lucas’s when referring to something that belongs to Lucas. While both are technically correct, the main difference is in the required style guide.
It will always depend on the required style guide you need to follow, but the most important thing is that you stay consistent with it. If you use brother’s in one sentence, use Lucas’s in the next. If you use brothers instead, you will use Lucas’.
It is also important that you don’t make any exceptions during your writing process. Consistency will make a huge difference. You will also need to make sure that the program you are writing on doesn’t automatically correct it to the opposite.
Most people will just follow what their friends and family use. This will ensure that everyone is on the same page, but it might not always be best in a professional situation. Always make sure to follow the style guide that is used by the company or person you are writing for.
If you really aren’t sure which to use and you don’t want to make a mistake, you can keep things simple. Instead of saying Lucas’ or Lucas’s, you can just say that it belongs to Lucas.
