彼は兄弟がいます actually 彼には兄弟がいます with に omitted


I read this [Is it correct to say
私は二人のお兄さんがいる?](https://japanese.stackexchange.com/questions/32770/is-it-
correct-to-

and it says it's unnatural if you don't use には. But a lot of native speakers
corrected my incorrect sentence of

> 彼に兄弟がいます。

to

> ①彼は兄弟がいます

Is there actually a に that is omitted in the corrected sentence so it is
actually

> ②彼(に)は兄弟がいます

Native speaker told me

So am I right to assume that ① is just used in casual settings?

And, I prepare

-「僕(に/には/は)兄弟がいません、でも彼(に/には/は)二人兄弟がいます。」 : _"I do not have any brothers, but he has two brothers."_

This sentence basically comparing one's siblings status. I think all of に, には
and は are interchangeable because it can imply comparison and also topic.

I mean repeating 「に」 twice sounds the sentence talks "comparison" and
repeating 「は」 twice sounds the sentence talks "topic" and using 「には」 twice
sounds the sentence talks topicalizing comparison. ( I think
僕は兄弟がいません、でも彼に二人兄弟がいます。is awkward. So, probably not repeating and mixing each
(に/には/は) in the sentence makes it awkward without knowing the context. )

But, saying「彼に兄弟がいます」as stand-alone is a bit awkward since it should be used
in a comparative structure.

Probably「彼は兄弟がいます」is bit abrupt to the native speaker's ear if you do not know
what you are taking about.

I agree with 「彼には兄弟がいます」is natural since it can be start-point of comparison
and topic.
