Cousin made my logos, took my headshots, now she wants me to delete it years later

r/

My cousin helped me with a few of my small businesses, designing logos, creating marketing materials, and taking branding photos of me (sometimes using a phone, sometimes her camera or mine). Some of these businesses haven’t been active in years, but I’ve continued using the photos with one small business. There is one logo I used in the past that I might want to use in the future, as I invested in product samples, guides and other marketing materials using that logo, it would be costly to redo all that and the logo has sentimental value. The others I have no plans of using in the future. I paid her for one of the logos (that business is closed) and the rest she offered as a favor. She used some of them in her portfolio and another for a school project where she needed to design branding. She has also used them in social media posts to market herself as she was just starting out, including sharing images I took of branded products (with my permission).

After a falling out, she sent me a message demanding that I remove every single asset she’s ever touched, and stop using any logos, photos, or branding she ever helped with, even from businesses that have been closed for years. She wants all old social media posts with her images, logos, etc. going back more than 10 years taken down, including non-active business social media accounts. I’ve used some of the images repeatedly in my current business for informational carousel social media posts, which are extensive in number, and would take me a substantial amount of time to recreate and/or remove these. Many also include logo watermarks.

She gave me 2 weeks to remove everything or work out a licensing agreement and implied legal consequences if I don’t. Given her current attitude, I don’t believe she would offer a fair price for licensing, and would likely offer a price she knows I cannot afford, so I feel licensing is an empty offer.

I’m being told to erase logos I paid her for, headshots she took as a favor (and knew I was using for branding). I have texts confirming delivery and payment for one logo, and all the photos have been used publicly with her knowledge and without any objection until now.

Can she legally force me to stop using this stuff after years of liking the posts on social and even showcasing the work in her own portfolio and business social media accounts?

Location: Indiana, but some photos were taken in California, if that is relevant.

No contracts, this was a friendly, family exchange, but she verbally told me I could use them and they were specifically created for my business use. We often collaborated and helped each other out.

I’ve already removed images from my current, active website since that was a quick fix.
