In the context of the Philippines, the proliferation of conflict of laws cases has been due to and a result of technological advancements in communication and transportation. It used to be that persons and property were confined within a certain territorial jurisdiction, owing to lack of interest or means in travelling to another. Hence, in the early years of Philippine law, the application of foreign laws was least of the concerns of courts. Later, the advent of ships, planes, trains and so on have led to transboundary movement of persons and property.

Due to said advancements, it is now no longer unusual to find persons in places not their country of origin and incidents of property – such as ownership and possession – involving two or more systems of laws. These persons later find themselves in legal relationships with foreigners and their pieces of property later get exposed to the legal consequences of different states’ laws.

Consider an example about a Filipino man and a Canadian woman who had their marriage solemnized in Japan. Should a legal question arise in the Philippines concerning the validity of this marital union, a Philippine court would be compelled to invoke the forum state's choice-of-law rules to ascertain the governing legal framework over the case. In matters pertaining to the formal validity of marriage, Philippine jurisprudence generally adheres to the principle of lex loci celebrationis, thereby potentially subjecting the marriage's extrinsic validity to the laws of Japan, the place of its solemnization. Of course, the intrinsic validity of this contract of marriage is another issue covered by a different choice-of-law approach.

Furthermore, if the same couple establishes their domicile or habitual residence in China, their legal connection to that jurisdiction may become pertinent in various legal contexts such as but not limited to citizenship of their children, the ability to dispose of real property in China and many more. Should the dissolution of their marriage become a consideration while residing in China, a Philippine court might be required to consider Chinese law, particularly concerning aspects directly influenced by their status as domiciliaries there. Please note that the validity of marriage between a Filipino and a foreigner may still be within the jurisdiction of Philippine courts even if they are residents or domiciliaries of a different country.

In contrast, any real or personal property owned by the same couple within the territorial jurisdiction of the Philippines would typically be governed by Philippine law, in accordance with the principle of lex rei sitae. Nevertheless, in the event of the death of one of the spouses, the disposition of these Philippine-based assets could -- not "should" -- necessitate consideration of their respective national laws -- Filipino and Canadian -- particularly in matters of intestate or testamentary succession. This is because Philippine law delineates specific provisions regarding legal heirs and their corresponding entitlements to the inheritance, which may be different from those provided under Canadian law. Moreover, the validity of any testamentary instrument executed abroad would still be subject to scrutiny under Philippine legal standards if submitted for probate before a Philippine court or if the decree of allowance of a will obtained abroad is sought to be enforced in the Philippines.

In addition to the above illustration, the following paragraphs are other scenarios in which technological advancement evidently give rise to private international law problems.

When a Filipino consumer engages in a purchase via an online platform based in Singapore, any ensuing dispute regarding the transaction's terms and conditions or the quality of goods may necessitate a determination of whether Philippine law, Singaporean law, or potentially the law of the jurisdiction hosting the platform's servers should govern the resolution. The presence of a choice-of-law clause within the platform's terms and conditions could also be a decisive factor.

Many Filipinos work abroad and often enter into employment contracts that are subject to foreign labor laws. Should overseas Filipino workers (OFWs) sustain injuries in their workplace in, for example, Saudi Arabia, and subsequently return to the Philippines, a legal inquiry concerning jurisdiction, prescription, compensation and liability may arise. Philippine courts might then be required to consider Saudi Arabian labor regulations, the specifics of the employment agreement, and potentially Philippine laws designed to protect the rights of overseas workers.

When a Japanese corporation invests in a manufacturing company registered and existing under the Philippines, potential legal disputes concerning the propriety of such investment is often governed by Philippine laws. Also, whether or not a majority of members of the board of directors (BOD) or a supermajority is required to constitute a quorum is an internal business matter that is often governed by the laws of the state that gave its imprimatur to the legal existence of the investing corporation.

The process by which Filipino individuals or couples seek to adopt a child from a foreign country, such as Vietnam, may involve adherence to the adoption laws of both the Philippines and Vietnam. Issues pertaining to the eligibility of prospective adoptive parents, the consent of biological parents, and the paramount welfare of the child are subject to evaluation under both legal frameworks. In the Philippines, intercountry adoption is allowed, subject to certain condition not imposed in ordinary domestic adoption processes.

In instances where a Filipino artist creates digital artwork that is widely disseminated and potentially subjected to copyright infringement across international borders, the determination of which nation's intellectual property laws are applicable and the enforcement of those rights necessitate navigating the complexities of conflict of laws. Note, however, that there exist international systems for the protection of intellectual property around the world.

As can be seen in the discussions above, technological advancements have facilitated increased global interaction and have profoundly influenced the legal landscape of the Philippines, leading to a marked increase in the frequency and complexity of conflict of laws cases that find themselves in the dockets of courts and eventually in the hands of the Supreme Court. As a result, Philippine courts are now routinely called upon to address intricate legal issues that necessitate a nuanced understanding and application of foreign legal principles, guided by established choice-of-law doctrines. The aforementioned examples serve to illustrate the diverse contexts in which these principles are invoked, underscoring the growing significance of conflict of laws in an increasingly interconnected world.
