哈同夫婦冇生過仔女，哈同係領養咗11個外籍孤兒做養仔女，而羅迦陵就領養咗9個華籍孤兒做內侄仔女。1931年6月19號哈同喺愛儷園因病離世，留低咗高達一億七千二百萬元（$150，000，000）嘅巨額遺產，單係羅女繳納嘅遺產稅就達1，800萬元。羅女跟著喺1941年過埋身，因兩夫婦留低嘅遺囑有好大出入，引發咗曠日持久嘅哈同遺產案。1954年，中共政府徵用咗愛儷園，重新起過變成中蘇友好大廈（宜家嘅上海展覽中心）。
The Hartung couple never had children, Hartung adopted 11 foreign orphans as adopted children, and Luo Jialing adopted 9 Chinese orphans as nephews. On June 19, 1931, Hartung died of illness in the Garden of Elle, leaving behind a huge inheritance of 172 million yuan ($150,000,000), and the inheritance tax paid by his daughter alone amounted to 18 million yuan. Luo Nu died in 1941, because the wills left by the two couples were very different, which led to a protracted Hahe inheritance case. In 1954, the Chinese government requisitioned the Aili Garden, which was rebuilt into the Sino-Soviet Friendship Building (IKEA's Shanghai Exhibition Center).
